Took my 740i to the drag strip yesterday and it did alright i guess. Bald 225 tires hindered my time i think. next time i visit im putting in a 4.10 ratio diff and sticky 245 tires. that should get me into the 13's. anyways here are my best two times.
EDIT: i just realized today that my 740i has not had the 02 sensors installed since ive had it. no bung on the pipes to put them in. so even with my DUDMD chip, the DME must be running a rich fuel mixture and retarding the timing 2 degrees since it has no way of knowing how to determine the air fuel mixture. Or i may not even be receiving a better fuel/ignition map from the chip at all if its stuck in closed loop. i knew there was a reason the car didnt run a better time
